If you want to pack your files into RAR’s then use this simple Terminal command

rar a -v100000 MySplitRarArchive

where -vxx is the file size of each of the RAR files in kb’s

A friend of mine has an “old” iBook G4 and was trying to get it to connect to her wireless network via Airport, however she couldn’t establish a connection, after trying to manually type IP details into the Network Preferences pain and having no luck, then renewing the DHCP details with no luck I thought id hit a brick wall.

The issue is an obvious one that only seems to affect 10.5.2 and the fix is very simple, its the firewall that is causing the issue. Within System Preferences under the Security section, tab to Firewall and set it too “Allow all incoming connections”, this will then magically fix the DHCP issue, now the internet connection is working it can be updated to the latest version of Leopard (10.5.8)
